Personal utility knife.........?

I picked up this neat 'multi' knife and leather pouch at an Antique Mall
several years ago for a great price. It is marked 'D.R.G.M.' and has
the logo for 'Muller & Schmidt, Pfeilringwerk, Solingen' - who were
in business during the Third Reich era - which I recognised
and was the reason I bought it.

The ribbed scales are made of aluminum, and the corkscrew is
grooved - much like earlier Swiss Army Knives. The blade
is etched 'PRAKTIKATOR', and the pouch has a snap
that is marked 'P-R-Y-M'.........
